Blockchain Technology is the first successful Bitcoin Network. It enables the ledger to become more decentralized and secure. Since it is not limited to bitcoin and controlled by third parties by government, corporations, or banks, the Technology is capturing several industries, including cryptocurrency, infrastructure& hardware, financial Technology, Internet & mobile and so on. Blockchain is used as a public ledger to verify all peer-to-peer system transactions and maintain traded bitcoin spending from central authorities while bitcoin has distributed transactions. Achieving high Blockchain-based performance and privacy & security are global issues that are desire to be overcome as claims show they are still significant challenges in many Blockchain applications. This paper presents an introduction to Blockchain and the process of this Technology in the way of outlining Blockchain types. Also, recent advances, challenges, real economy integration, and current situations of this Technology have been listed.

Medical drones are used to transport medical supplies, equipment, and personnel to remote and underserved areas, providing life-saving assistance to communities in need. However, the current system of medical supply chains is often inefficient and prone to errors, with little transparency and accountability. By incorporating Blockchain Technology into the medical drone system, it is possible to improve the transparency and security of medical supply chains, as well as the tracking and monitoring of medical drones. Blockchain can be used to securely store and manage information about medical drone deliveries, including the origin and destination of the drones, as well as the type and quantity of medical supplies being transported. Additionally, Blockchain can also be used to manage payments for medical drone services, ensuring that payments are securely and transparently processed, tracking the maintenance and repair of medical drones, and ensuring that they are in good condition and safe to use. In conclusion, the implementation of medical drones using Blockchain Technology has the potential to greatly improve the efficiency, security, and transparency of medical supply chains. This can help to ensure that medical supplies and equipment reach their intended destination.
